Liquiline Control CDC90

Endress+Hauser

Modbus TCP

NOTICE

The device uses an EtherCat connection for internal communication. Depending on the network

load, EtherCAT may cause failures in the CDC90 IPCs if multiple CDC90 devices are integrated

in the same network.

‣ To reduce the network load in the case of a Modbus TCP connection, the networks must be

separated. Physical separation with a VLAN-enabled switch, e.g. Layer 2 managed switch, or

software-based separation is possible.

Web server

The Liquiline Control's IPC features a web server that allows users to configure the device, visualize

measured values and check the status of the entire system.

The web server of the CDC90 control unit enables the direct configuration of the connected sensor

and peripheral modules for digital/analog inputs and outputs. The two web servers can be accessed

via separate IP addresses.
